Update devel/okteta to the latest version.

https://www.kde.org/applications/utilities/okteta

• Fixed: bad offset of elements in statusbar
• Translations improved (cs, en_GB, ga, lv, nn, pt)

While here, bump consumer devel/kdevelop (also the library names
have changed in innovative ways) and devel/kdesdk (which was still
worried about the KDE4 version of okteta).
